Ordinal notation: Art, List & Overview

In mathematical logic and set theory, an ordinal notation is a partial function mapping the set of all finite sequences of symbols, themselves members of a finite alphabet, to a countable set of ordinals. A Gödel numbering is an injective function mapping the set of well-formed formulae (a finite sequence of symbols on which the ordinal notation function…
